I'm 12. And my parents have never blocked anything from me..

My parents used to do that it was horrible

Just search in google how to get rid of parental control.

Factory Reset the computer. Type in Google "how to factory reset(your computer manufacturer)" and you should find a way to reset your computer.

My dad did something like this too. I just figured out his password made myself the administrator and controlled his profile

I'm sure there's stuff online about how to bypass the system. I wonder on his administration account there's a forgot password button that'll let you figure out what it is.

Or u know factory re set it . . .

Just take it to an Apple Store and have everything erased. Or do it your self.

You're almost on the right track, would work on XP if you haven't reset the default password. In windows 7 the local admin account is disabled by default. The only option is to remove the admin password by using Hirens, ERD or any other password cracker. Can be done in under 5 minutes.

That's why you set up passwords and parental controls (that allow everything) so they can't change it even if they wanted to
